Freezing temperatures. 17 hours of darkness. Miles upon miles of gruelling terrain. A brutal mix of ice, wind, hail, mud and snow. And maybe, just maybe, a glorious Scottish winter sunrise…

When it comes to mountain bike challenges, they don’t come much tougher or more rewarding than the Strathpuffer – the legendary 24 hour mountain bike endurance event held every year in the Highlands of Scotland in the middle of winter.
